Convection
Heat Transfer
Radiation
transfer of energy through empty space
no direct contact
Conduction
direct contact of particles of matter
Convection
movement of a heated fluid
convection currents
a flow that transfers heat with a fluid
stops when all the material has reached the same temperature
Convection in Earth's Mantle
responds to heat
heat source is the core
currents have been moving inside Earth for more than 4 billion years
